Water Heater Repair FAQs

Have questions about water heater repairs? Here’s what San Antonio homeowners often ask when their unit starts acting up.

What are common signs my water heater needs repair?

Look for lukewarm water, inconsistent temperatures, leaks, strange noises, or long heating times. These are signs your heater needs attention.

Can you fix tankless water heaters?

Yes, we repair both tank and tankless systems. Our team is trained to troubleshoot and repair on-demand water heaters.

How long should a water heater last?

Traditional tank heaters usually last 8–12 years, while tankless models can go 15–20 years with maintenance.

Should I repair or replace my water heater?

If your unit is under 10 years old and the problem is minor, repairs make sense. For older units with rust or multiple issues, replacement may be smarter.
